Improvement of the nutritional support management system for patients in intensive care units

BACKGROUND Nutritional support for patients hospitalized in the intensive care unit (ICU) is an important part of clinical treatment and care, but there are significant implementation difficulties. AIM To introduce a modified nutritional support management system for ICU patients based on closed-loop information management and psychological counseling. METHODS The division of functions, personnel training, system construction, development of an intelligent decision-making software system, quality control, and improvement of the whole process were carried out to systematically manage nutritional support for ICU patients. RESULTS Following the implementation of the whole process management system, the scores of ICU medical staff's knowledge, attitudes/beliefs, and practices regarding nutritional support were comprehensively enhanced. The proportion of hospital bed-days of total enteral nutrition (EN) in ICU patients increased from 5.58% to 11.46%, and the proportion of EN plus parenteral nutrition increased from 42.71% to 47.07%. The rate of EN initiation within 48 h of ICU admission increased from 37.50% to 48.28%, and the EN compliance rate within 72 h elevated from 20.59% to 31.72%. After the implementation of the project, the Self-rating Anxiety Scale score decreased from 61.07 +/- 9.91 points to 52.03 +/- 9.02 points, the Self-rating Depression Scale score reduced from 62.47 +/- 10.50 points to 56.34 +/- 9.83 points, and the ICU stay decreased from 5.76 +/- 2.77 d to 5.10 +/- 2.12 d. CONCLUSION The nutritional support management system based on closed-loop information management and psychological counseling achieved remarkable results in clinical applications in ICU patients.
